19 This perfect quiet of the mind, in which we enjoy the loving God by returning His love, and by which we turn and direct ourselves and all we have to Him, does not make us lazy and slothful. Rather it is a constant, effective and active zeal that spurs us on to look to our own salvation, and, with the help of God, to that of others also. For this lofty contemplation and meditation, which is brought about by divine love, "regulates the affections, directs the actions, cuts away all excesses, forms the character, orders and ennobles the life, and lastly. . . endows the understanding with a knowledge of things divine and human. It . . . undoes what is tangled, unites what is divided, gathers what is scattered, uncovers what is hidden, searches out what is false and deceptive. It . . . lays down beforehand what we have to do, and passes in review what has been accomplished, so that nothing disordered may remain in the mind, nothing uncorrected. Finally . . . it makes provision for trouble, and thus endures misfortune, so to say, without feeling it, of which the former is the part of prudence, and the latter the function of fortitude."
